Is it possible to turn acrylic that's been glued to wood?

Topic tags/keywords: plastic adhered to wood acrylic ca glue turning spindle lathe

I am thinking that it would probably depend on the type of glue being used. This is CA glue.
I’m trying to think of the best way to make a wooden wand with an acrylic topper.

Thank you
Nikki

I wouldn’t depend on glue alone, attach using a mortise and tenon, maybe pinned.

Sorry. This is for a wand spindle so I’m not sure that would work. It’s a fairly thin spindle . It hasn’t been glued to flat flush surfaces but was pinned with a peg first.

My main question is can this be turned together or will the glue interfere with the turning?

Or would I be best off finishing the stick separately and the acrylic topper separately and gluing them at the end so it covers up the ugly glue line.

My expectation would be that the acrylic piece will not stick if turned together with only glue. I don’t fully understand your reply or why a mortise and tenon wouldn’t work or what is pegged so I could be misunderstanding. I’ve used tenons in spindles the size of a pencil.

Thank you Rick. I’m not having a problem gluing the two materials together except for where it’s attached.

So are you saying that unless a have a more secure connection,turning might be pointless because it’s not strong enough?

So if this connection IS strong enough, it is possibly to turn the two together?

It’s hard to say without knowing exactly what you’re doing.

Most plastics are difficult to glue to other materials, as most glues don’t adhere well to plastics.

Ok thanks. I haven’t had any problems gluing them. In fact I can’t even detach them at this point.
I think what I’ll do is just try turning it together and see how it goes. I just wasn’t sure if I was missing something.

If they are stuck tight then go for it. Like Gerry said, most glues don’t adhere well to plastics. CA glue is strong in tension but weak in shear strength so I would expect it to pop off if there is much turning left but I’ve never tried it so can’t say for sure. I’m curious how it works out, hope you will let us know.

Hi Rick.
I was going to turn it tonight but I’ve got a killer cold. Didn’t have one all winter, but as soon as the weather gets ridiculously awesome, I get struck with this. : /
Yeah! I know ! Keep the whining to myself. lol.

The good thing is there isn’t a lot of torque pressure at the place where they are attached which is reassuring.

I’ll go out and spin this tomorrow

Thanks Rick

You could try that Gorilla glue! I have seen that glue hold two pieces of polyethylene together without letting go.
The problem will be how to remove it once you are done.

Just a thought!

Yes indeed. I have some of that also. In fact I’ve got all kinds of resins, glues and compounds but that guerrilla glue kicks butt. I’ve stuck my fingers together a couple of times. Also have to rip the skin off to get them apart.

Ive got to add that exoerimenting is fun and usually where I learn the most. One thing I need to start doing is taking notes. My memory is not good enough to remember everything I’ve tried.

Thanks for the help guys. I’m feeling very welcomed at the site. :D

I’ll let you know how the experimentation goes.

I just want to point out that you have to be very careful with any super glues because they can whiten the acrylic.
Glues like super glue or guerrilla glue I usually only use with wood. Some chemicals just don’t mix well together.

Did it work?
I didn’t try it this way . I found an easier way so went with that. It might not be easier but it worked. I made the topper and just glued it and I can’t pull that off with all my effort so for now that’s what I’m going with. It actually worked quite nicely.
Not really sure how to add a photo.

We turn acrylic for pens and, of course, wood. We also turn wood filled with cracks filled with epoxy. As such, if you’ve got a good joint, and sharp knives, there is no reason not to jump in with both feet [and a safety shield].

Thanks Kelly,
We have excellent tools and it’s not that I’m afraid to do this now. In fact I do really want to try it because the other way there’s a lot of fiddling around which I’m not a fan of.
We just got hit with some brutal weather and the lathe is in the garage which is not insulated so it’s mighty cold.
At the moment I’m power carving and can’t seem to pull myself away. This is truly the bomb.
I will update once the weather warms up once more.
We went from 75 degrees to 32 with snow in a matter of days which really kinda sucks but I’ll live. Lol
Thanks fellow members.
